Not entirely. A vessel will float provided its displaced weight is such that there is ample freeboard remaining. If there is no freeboard, there will be nothing to prevent the water from coming inboard and sinking the vessel. On a small boat, buoyancy bags will prevent the boat from sinking to the bottom of the sea, even if filled with water.
The force that makes things float is called buoyancy.
Floating, or buoyancy, depends on the density of the liquid and the density of the object. Water is a pretty dense liquid, and things float in it; they are buoyant. Oil or gasoline are less dense; things that float in water may not float in oil.
The salt in the water causes everything to have more buoyancy (Meaning it makes things more likely to float.) If you die in the ocean your body is more than likely going to float unless it is attached to something heavier is attached.
buoyant force
Buoyancy force is what causes things to float in water. To calculate buoyancy, use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec). It is also density that makes things float in water. If the object has less density than water, it will float.
Buoyancy is an upward lifting force, which means in the water buoyancy can make things float, for example: a rubber duck, pineapple, softball, etc. And that of buoyancy can make you float in the water.
because of buoyancy!
The force that makes things float is called buoyancy.
The term for the scientific explanation of how things float is "buoyancy."
Buoyancy
The property of water that allows things to float is buoyancy. Water exerts an upward force on objects placed in it, which counteracts the force of gravity pulling the objects down. This buoyant force is what allows objects to float in water.
Density of the object and buoyancy of the water/liquid.
Objects can float when they are less dense than the liquid they are placed in. This creates an upward force called buoyancy that helps keep the object afloat. By adjusting the weight or shape of an object, you can make it float in water or other liquids.
Things float in the air when the force of buoyancy (upward force exerted by air or a fluid) is greater than the force of gravity (downward force pulling objects toward the earth). This is known as buoyancy and is what allows objects to float or stay suspended in a fluid or gas like air.
High buoyancy=easy to float
It depends on the buoyancy of an object in relation to the liquid it is in.
Buoancy is the upward force that keeps things floating. I guess it doesn't need surface tension.. http://en.wikipedia.org/wiki/Buoyancy
